Some extremely hot and humid days may surprise you, and while you are busy at work, symptoms of heat exhaustion appear, and you may develop this condition without realizing it. In a few hours, your condition may turn into a medical condition that requires rapid intervention, so follow with us this article, which contains valuable information that explains to you the meaning of heat exhaustion, its symptoms and stages, along with the most important effective treatment methods.
What is heat stress?
Heat Exhaustion is a condition that a person suffers from as a result of prolonged or severe exposure to high temperatures or high humidity, which causes the body to lose large amounts of fluids and salts through excessive sweating. This imbalance causes the body to lose the ability to regulate its internal temperature, causing many disease symptoms.
Symptoms of heat stress
Symptoms of heat stress appear to alert the body to the presence of danger and indicate that it is entering a stage of complete exhaustion and requires rapid intervention. The most important of these symptoms are the following:
- Excessive and profuse sweating because the body is trying to reduce internal temperature.
- Nausea and vomiting are a result of the effect on the digestive system due to heat and dehydration.
- Pale, cold, and clammy skin due to loss of salts and fluids and decreased blood flow to the skin.
- Feeling extremely thirsty as the body tries to compensate for the lost fluids and get rid of dehydration.
- A state of fatigue and muscle weakness due to low energy and a severe disturbance in the mineral balance.
- Headache due to loss of salts, along with dizziness and vertigo as a result of low blood pressure and lack of fluids in the body.
- Unexplained signs such as an accelerated heartbeat in an attempt to deliver oxygen to the body's organs, along with rapid breathing.
- In some advanced stages, the ability to concentrate decreases, with mental confusion and temporary loss of consciousness.

What are the five stages of heat stress?
The stages of heat stress are divided into five stages that differ in their severity and impact on the body, which are:
1. Heat cramps
Heat cramps are the beginning of heat exhaustion and appear with physical exertion in a hot place or that does not have good ventilation. At this stage, the affected person is exposed to muscle spasms and contractions in the legs and arms, and this stage is not accompanied by an increase in body temperature.
2. Heat exhaustion stage
Heat exhaustion is a moderate stage and can be controlled, but speed is required so that it does not develop into heat stroke. Its symptoms include profuse sweating with the signs we mentioned above, with the body becoming dehydrated due to the sudden loss of salts and fluids.
3. Fainting or heat dizziness
The victim is exposed to heat fainting as a result of a sudden drop in blood pressure and dilation of blood vessels in the skin. Symptoms include dizziness and blurred vision, along with a feeling of fainting when trying to stand. This condition may seem more difficult due to the sudden blood flow to cool the skin, which reduces blood access to the brain.
4. Heat rash
The stage of heat rash is more advanced, and includes the appearance of the rash as a result of blockage in the sweating ducts in the skin. Its symptoms include skin itching, tingling, and red blisters in areas of friction, and its treatment requires medical intervention to quickly cool the skin.
5. Heat stroke
Heatstroke is the most dangerous stage of heat exhaustion and requires rapid medical intervention because the body becomes completely unable to regulate internal temperature. We will learn in detail the difference between heatstroke and heat exhaustion in the following paragraph.
What is the difference between heat stroke and heat exhaustion?
We present to you, dear reader, the following detailed table that shows you the difference between heat stroke and heat exhaustion:
| Difference points | Sunstroke | Heat stress |
| Reasons | Failure to regulate body temperature due to intense exposure to the sun. | With exposure to heat and sweating, the body loses fluids and salts. |
| What distinguishes its symptoms? |
|
|
| Body temperature | 40°C or more | Less than 40°C. |
| Danger | A serious condition that must be treated immediately. | Moderate and may develop into heatstroke if treatment is neglected. |
| Rapid treatment | Urgent medical treatment and emergency care. | Home treatment includes cooling the body and drinking fluids. |

Heat stress treatment
Treatment for heat stress varies depending on the stage the patient has reached and the extent of the body’s response. Treatment is divided into:
1.First aid
There are some steps that can help reduce symptoms and cool the body quickly after mild or moderate heat exhaustion. These steps include the following:
- Immediately move to a shaded, cool place with a good source of ventilation.
- Complete rest for the injured person. It is preferable to lie down and raise the feet to improve blood flow to the heart.
- Cool the body quickly by applying cold compresses to the head, neck and underarms.
- Loosen clothing and take a lukewarm bath or spray the body with cold water to reduce the internal temperature.
- Drink cold fluids that contain lost salts and minerals, such as potassium and sodium.
- Monitor symptoms and follow up moment by moment, and if the body does not improve within an hour, seek medical care.
2. Medical treatment in hospital
Some cases may not show a quick response to attempts to cool the body at home and administer first aid and require medical intervention in the hospital, which includes the following:
- A comprehensive assessment of the condition and measuring body temperature, blood pressure, and heart rate, along with an analysis of the percentage of salts in the blood.
- Rapid medical cooling, which includes special devices to cool the body with ice compresses in specific areas of the body.
- Giving the injured person intravenous (IV) treatment or an intravenous solution that quickly compensates for the loss of fluids and salts in the body.

Frequently asked questions
Below we learn about the most common questions we receive about heat exhaustion, and answer them in detail:
Is heat exhaustion dangerous?
At some stages, heat exhaustion may become dangerous, especially if prompt treatment is neglected, because the body loses a large amount of salts, which weakens the heart muscle and affects brain functions.
Does heat stress cause sore throat?
No, heat stress does not directly cause a sore throat, but the loss of fluids results in dryness of the body and throat, and rapid breathing in this case causes dryness in the mucous membranes, which makes you feel like you have a sore throat.
How do you know if you are suffering from heat exhaustion or heat stroke?
If you feel profuse sweating and coldness in the body, you know that you are suffering from heat exhaustion. However, if you feel that the sweating has stopped with extreme heat in the skin, then you are suffering from heatstroke. In both cases, contact the emergency department at Al-Mousa Specialist.
